Copies and e-way bill
Prepare the challan in triplicate: original for the consignee, duplicate for the transporter and triplicate for the consigner (Rule 55(2)). When goods move on a challan, they are declared in an e-way bill as Rule 138 requires: generally when the consignment value exceeds ₹50,000, and for some movements such as inter-state transfers to a job worker whatever the value.
Goods sent in parts (for example a machine in knocked-down condition) go with the full tax invoice issued before the first lot, and a challan with each lot that refers to the invoice (Rule 55(5)).
Job work
Inputs sent to a job worker must come back within one year and capital goods within three years, or the movement is treated as a supply from the day they were sent (section 143 of the CGST Act). Keep the challan number to match the return.
Common mistakes
- Using a challan for an ordinary sale to avoid issuing an invoice.
- Not recording the challan in the e-way bill when one is needed.
- Losing track of goods at job workers past the time limit.
